SPRING-LOCK AUTUl'IOBILE-RM.

Application filed April 30. 1917. Serial 165,493.

T 0 all 'whom it may concern:

Be it known that we, OTTO J. PBTRASCHKE and ROBERT H. ZWICKEY, citizens of the United States, residing at Verona, inthe county Vof Dane and State of lVisconsin, have invented certain new and useful lmprovements in Springlsoclr Automobile- Rims, of which the following is a specification.

This invention relates to new and useful improvements in automobile wheels and the .principal object of the invention is to provide means t'or quickly and easily securing the rim, carrying the tire on the wheel.

Another object of the invention is to prof vide means on the rim engaging with means on the `telly for positioning the rim on the wheel.

Another object of the invention is to provide projections on the rim engaging slots in the telly and pins passing through holes in the telly and engaging with holes in the project-ions for holding the rim in place and spring means for holding the pins in the holes.

A further object of the invention is to provide means for securing the two ends of the rim together.

Another object of the invention to provide a device of this character which is simple and durable in construction. reliable and efcient in operation and one which can loe manufactured and placed upon the market at a minimum cost.

The invention also consists in certain other features of construction and in the combinationand arrangement of the several parts, to be hereinafter fully described. illustrated in the accompanying drawings and specifically pointed out in the appended,

claims.

In describing our invention in detail, reference will be had to the accompanying drawings, wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure l is an elevation of part of aavheel supplied with our invention.

Fig. 2 is a longitudinal, sectional view.

Figs. 3 and 4 are details.

In these figures, 'l indicates the wheel having its telly 2 provided with transverse slots 3 and these slots are to receive lugs 4 located on the under side of the dcmountable rim 5 which carries the tire 6. We prefer to malte the slots fl of wedge shape, as

Specification of Letters Patent.

malte the lugs Il of corresponding shape.

indicates pins passing through holes S ini..

the felly into a hole 9 in the lug 4 and a spring plate l0 secured to the under side of the telly at l1 has a hole 12 for receiving the reduced end of the pin to hold the same 1n place. 13 indicates a metal plate secured to the under side or" the felly adjacent the hole 8 and having a hole therein registering with said hole 8 and this plate carries a pair ot' lugs le for engaging the end of the spring plate l0 to hold the same in engagement with the pin. rIlle space between vthese two lugs `is smaller than the width of the spring so that the spring must be 'forced between the lugs so as to be held thereby.

vWe prefer to separate the rim as at l5 and we secure the two ends of said rim together by means of the latch 16 secured to one end of the rim engaging a pin 17 secured to the other end. The numeral 18 desigvstates formed in the abutting ends ot the rim and 19 indicates pins carried bj one end and engaging holes 2C' in the other end.

After the tire is placed on the rim. the ends of the same are locked together by means et the latch i6. rllhe rim is then slid sidewise onto the wheel with the lugs el engaging the slots and after the rim is in position the pins 7 are inserted and then the spring plates 10 are :forced into position to hold the pins in place. rlf'hus, the rim is securely held in place and cannot be removed from the wheel until the spring plates l0 are forced from between the lugs 14 by means of pliers or the like. after which the pins 7 are removed and then the rim may be slid sidewise od the wheel.

lt is thought from the foregoing that the advantages and novel features of our inven-A tion will be readily apparent.

lVe desire it to be understood that we may make slight changes in the construction and in the combination and ar angement of the rate-atea. nee. le, raie. l

several parts, provided that such changes` gaged between the pairs of the lugs for holding said pins in position.

In testimony whereof we affix or signatures in presence of two witnesses.
